Description: The CV Series of transient surge suppressors is disc-shaped varistors that can be operated continuously in low and medium voltage electronic circuits, as well as across AC power lines. Due to their radial lead construction, these components require very little mounting space. They are available in five model sizes from 5 to 20mm and feature a wide range of AC operating voltages from 50V to 680V. Features: AC operating voltage (Vrms) from 50V to 680V DC operating voltage (Vdc) from 65V to 895V Broad range of current and energy handling capability For RMS voltages 40V see ZV leaded series 5 model sizes available from 5mm to 20mm UL, CSA, CECC approved +85ºC continuous operating temperature Lead free Climatic Category 40 / 85 / 56 Operating Ambient Temperature -40ºC to +85ºC In accordance with CECC 42000/42200/42201 Storage Temperature Range -40ºC to +125ºC Threshold Voltage Temperature Coefficient < +0.05% / ºC Isolation Voltage Capability > 2.5kV In accordance with CECC 42000/42200/42201 Response Time General Technical Data < 25 ns Insulation Resistance > 1 Gohm In accordance with CECC 42000/42200/42201 Standard Packaging Options Disc Diameter Series Range (Vrms) 5mm 7mm 10mm 14mm 20mm Reel Bulk Reel Bulk Reel Bulk Reel Bulk Reel Bulk 50-75 1,500 1,500 1,500 1,500 1,300 600 700 500 600 300 95 1,500 1,500 1,500 1,000 1,300 600 600 500 600 300 115-130 1,300 1,500 1,300 1,000 1,000 500 600 500 500 300 140-150 1,200 1,500 1,200 1,000 1,000 500 600 500 500 300 175 1,200 1,500 1,200 1,000 1,000 500 500 500 500 300 230 1,000 1,000 1,000 1,000 1,000 500 500 300 400 300 CV 250-275 1,000 1,000 1,000 1,000 800 500 400 300 400 300 300 900 1,000 900 1,000 800 500 400 300 400 200 320 N/A N/A N/A N/A 800 500 400 300 300 200 385 N/A N/A N/A N/A 700 400 400 300 300 200 420 N/A N/A N/A N/A 700 400 300 300 300 200 460-550 N/A N/A N/A N/A 600 400 300 300 300 200 625 N/A N/A N/A N/A 600 400 300 300 250 200 Rev Date: 05/13/2014 1 www.seielect.com
